half past [hour]

You say this to tell someone that it is 30 minutes after the hour you name.

For example, “half past six” means 6:30. This way of telling the time is common in British English; in American English, people also often say “six thirty.”

• The bus comes at half past six, so let's leave now.
• What time is lunch? — Half past twelve.
• I'll meet you at half past three by the café.
